Abstract: Apparatus and methods for unloading and binding brick or other components include an infeed conveyor that delivers layers of brick to a transfer distribution carriage. The distribution carriage repositions the brick layers on either an outfeed conveyor or a tine conveyor. The layers of bricks carried by the outfeed conveyor are moved to where a tine layer is positioned on their upper surface. The tine conveyor divides the bricks into an arrangement of rows spaced apart to define openings for receiving a lifting or moving member, so that when the tine layer is positioned in a completed stack, enables movement of the stack by a forklift or other suitable moving means. Additional layer or layers are then positioned on the tine row on a packaging conveyor so that completed stacks are delivered to a package station that binds the stack of bricks or other components into an integrated structure.

Abstract: A security gate is coupled via a positive-drive mechanical linkage to a DC gear motor, operative in response to a defined output voltage profile, to provide precise rotation and counter-rotation of the security gate through a defined range of motion.

Abstract: A work table supports a grid of green brick aligned in longitudinal and transverse row for indexing movement by a hydraulic cylinder actuated pusher. The brick are indexed longitudinally beneath a first transverse row of embossing devices in a transverse row aligned with one embossing device being over every other brick of the transverse row. Following actuation of the first transverse row of embossing devices the brick are indexed beneath a second transverse row of embossing devices each of which is aligned with the brick that were not embossed by the first transverse row of embossing devices. Ramps are provided below the rows of embossing devices to elevate the brick above the next adjacent rows so that the brick being embossed is at a higher elevation than the adjacent brick.

Abstract: Surface acoustic wave devices with selectable performance parameters such as having a temperature coefficient of zero, may be fabricated employing a monocrystalline semiconductor substrate with a combination of appropriate doping and crystallographic orientation both with respect to the surface and the direction of propagation. Monocrystalline silicon doped with phosphorous to the order of 2.times.10.sup.19 atoms per cc, exhibits a zero temperature coefficient at 300.degree. Kelvin for acoustic waves propagating in the [110] crystallographic direction on a [110] substrate.
